wait

问题 Ran across the following problem in bxslider- how can you apply different delays between slides in the auto show? 回答1: I came up with the following solution which I will show here: in the jquery.bxslider.js replace: el.startAuto = function(preventControlUpdate){ // if an interval already exists, disregard call if(slider.interval) return; // create an interval slider.interval = setInterval(function(){ slider.settings.autoDirection == 'next' ? el.goToNextSlide() : el.goToPrevSlide(); }, slider

问题 I'm trying to write a program with 2 classes, a controller and a class that does a lot of computation. The controller creates a couple instances of the other class, then tells them all to start their calculations (in parallel). They each return when they are finished, and the controller resumes, and then, some time later, the controller passes them new data, and has them run the calculation again. Ideally, I would be able to call start() with parameters, but that isn't possible, so the

问题 How do I get PowerShell to wait until the Invoke-Item call has finished? I'm invoking a non-executable item, so I need to use Invoke-Item to open it. 回答1: Unfortunately you can't by using the Invoke-Item Commandlet directly.

问题 I have a class which initiates a sensor listener when it is started. This listener writes the latest sensor value to a variable when an event is triggered. The class goes on to do some logic, and at some point, will check this variable and proceed depending on the value. My issue is that there's no guarantee that there is any value when the variable is read, since Android sensor listeners only trigger an event when the sensor value changes (and don't necessarily trigger an event as soon as

If you want the commands to block and not do anything while it is executing, you can just use subprocess.call . #start and block
